Okwu mmalite
5-Methyl-6,7-dihydro-5H-cyclopentapyrazine. Ọ bụ kristal na-acha ọcha siri ike nke yiri kristal ma ọ bụ ntụ ntụ n'ọdịdị. Ngwa ahụ kwụsiri ike na ụlọ okpomọkụ, ma jiri nwayọọ nwayọọ decomposes n'okpuru omume nke elu okpomọkụ, ìhè ma ọ bụ oxygen.
5-Methyl-6,7-dihydro-5H-cyclopentapyrazine nwere ọtụtụ ngwa ngwa. Ọ bụ ọgwụ ahụhụ dị irè nke a na-eji n'ọrụ ugbo iji chịkwaa uto na mmeputakwa nke pesti.
Enwere ụzọ abụọ isi kwadebe 5-methyl-6,7-dihydro-5H-cyclopentapyrazine. A na-enweta otu site na mmeghachi omume condensation nke N-methylpyrazine, mgbe ahụ, a na-eme mmeghachi omume hydrogenation iji nweta ngwaahịa ezubere iche. A na-emepụta nke ọzọ site na mmeghachi omume oxidation na mbelata nke 5-benzoyl-6,7-dihydro-5H-cyclopentapyrazine.
Ozi nchekwa: 5-Methyl-6,7-dihydro-5H-cyclopentapyrazine bụ ihe na-egbu egbu. O nwere ike inwe mmetụta na-akpasu iwe na usoro ụjọ ahụ na iku ume na-akpasu iwe na akpụkpọ ahụ na anya. Usoro nchedo onwe onye kwesịrị ekwesị dị ka iyi akwa mkpuchi, uwe aka na ọta ihu ka achọrọ mgbe a na-arụ ọrụ. Ekwesịrị ịchekwa ihe ahụ n'ime akpa ikuku, pụọ na mgbanye ọkụ na oxidants. Mgbe ị na-edozi ihe ahụ, ekwesịrị ịzere uzuzu na ikuku ikuku, na iku ume na mmetụ akpụkpọ ahụ kwesịrị izere. Ọ bụrụ na ikpughe pụtara, were ọtụtụ mmiri sachaa ozugbo wee chọọ nlekọta ahụike. Mgbe ị na-ejikwa ma na-eji 5-methyl-6,7-dihydro-5H-cyclopentapyrazine, jiri nlezianya soro usoro nchekwa dị mkpa.
